Present situation : 1979 J20 w/Cummins T18 Dana20 with divorced Over/Under
Right now the truck tops out at 55mph so I'm assuming it is in the Off or Underdrive setting. I did not find the switch on the stick and after crawling underneath I found that the wiring harness is not hooked up to anything. After downloading the US Gear PDF I found out what the Control Module looks like and will go back and take another look to see if/where it is.
I tried searching forums and googled like a madman, but haven't found a source for any replacement parts. I'd imagine the selector switch would be something that could be cross referenced, but haven't found one yet much less the Control Module. Can anyone point me in the right direction?
